Your shrub requires a few days of hands-off time. While you are waiting, mix up a batch of strawberry-infused gin. Just add 1 pint of fresh, clean strawberries (with their tops cut off) to a 750 ml bottle of gin and wait about one week. Strain, and you’ve got strawberry-infused gin!
- In a cocktail shaker, add the strawberries, spearmint leaves and shrub. Muddle gently by pressing and turning the muddler into the fruit and mint. You are looking to release the juices and oils by doing this. If you do not have a muddler, you can use a wooden spoon for the same effect.
- Add the Cointreau, gin, and bitters and fill with ice. Shake vigorously.
- Strain the cocktail over a rocks glass filled with crushed ice, or into a chilled coupe glass. Garnish with a strawberry and a mint sprig.
